Palm has released public beta version of the webOS Plug-in Development Kit (PDK), which  complements the webOS Software Development Kit (SDK), allowing developers to use C and C++ alongside the web technologies that power the SDK and mix them within a single app.

The company said that the new PDK enables new functionality, including immersive 3D graphics, and provides developers who have built games for other platforms a way to bring their titles to the webOS platform.

In January, Palm introduced 12 games built by four leading developers with early access to the PDK. Since then, more than 20 webOS titles have been launched by the early-access developers.

Katie Mitic, senior vice president of product marketing at Palm, said: “Palm webOS is the go-to platform for great games on two of the three leading carrier networks. We have both the developer tools and the hardware necessary for a world-class gaming experience, and an impressive portfolio of webOS game titles from top-notch developers to show for it.”

Developers can download the beta PDK, but distribution of games built with the beta PDK will require functionality provided in an upcoming Palm webOS update, the company said.
